The blind hole of the fourth connecting column 5221 is not connected with the outside, so the turbine cavity and the accommodating cavity will not be in airflow communication through the blind hole of the fourth connecting column 5221. The head of the screw can close the fourth connecting hole 13, so the accommodating cavity will not be in airflow communication with the outside through the fourth connecting hole 13. In this way, the sealing effect of the top cover 1 and the upper pipe body 52 after connection can be ensured.

[0044] The fourth connecting column 5221 can have a blind hole with sufficient depth and width to improve the cooperation stability of the screw and the blind hole of the fourth connecting column 5221; the fourth connecting column 5221 is arranged to form the blind hole of the fourth connecting column 5221, so that other parts of the fifth connecting surface 522 can be thin-walled, thereby making the structure of the air outlet interface simpler and lighter.

[0045] The utility model discloses a power device, and the connecting portion 61 is equipped with the fifth connecting hole 611 on the air inlet joint 6, and the bottom plate of the containing cavity has the sixth connecting hole 43, and the sixth connecting column 3122 in the volute 31 is arranged on the lower cover plate 312, and the blind hole is arranged on the sixth connecting column 3122, and the connecting piece passes through the fifth connecting hole 611, the sixth connecting hole 43 and the blind hole on the sixth connecting column 3122 to fix the air inlet joint 6 and the lower cover plate 312 to the bottom plate of the containing cavity. The hole wall of the blind hole on the sixth connecting column 3122 is provided with internal thread, the connecting piece is screw, and the connecting piece is sequentially passed through the fifth connecting hole 611 and the sixth connecting hole 43 and is screwed with the blind hole on the sixth connecting column 3122, so that the fixing mode of the connecting piece and the blind hole on the sixth connecting column 3122 can be simplified.

[0046] The blind hole of the sixth connecting column 3122 does not communicate with the turbine cavity, so the turbine cavity and the containing cavity do not communicate with each other through the blind hole of the sixth connecting column 3122. The head of the connecting piece can close the fifth connecting hole 611, so the turbine cavity does not communicate with the outside through the fifth connecting hole 611, so that the sealing effect of the air inlet joint 6, the bottom plate of the containing cavity and the volute 31 can be ensured. The sixth connecting column 3122 can have a blind hole with sufficient depth and width to improve the cooperation stability of the connecting piece and the blind hole. The sixth connecting column 3122 is arranged to form the blind hole, so that other parts of the lower cover plate 312 can be thin-walled, thereby making the structure of the volute 31 simpler and lighter.

[0047] The above is only the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement or improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
